When I free dive, I spend quite a lot of time checking the crevices and crannies in the rocks on the bottom. In essence, I tidepool even when the water's over my head. In the above shots, I'm standing, not swimming, and fairly dry.
I love tidepools, love the intricacies of kelp, and find something compelling in that starfish's patience for the returning tide. Something like all that, anyway.
